Abstract

The present invention relates to a kind of door closer or door operators, comprise its one end by the housing of closed with covers, spring in the housing and the spring take-up for this spring are installed.Even still can realize door closer or the door operators of useful spring take-up to provide a kind of long and narrow hole type, spring take-up comprises adjusting nut (4), this adjusting nut (4) is rotatably installed in adjustment screw (5), thus adjustment screw (5) is supported in the shoulder hole of lid (6), and also can pass lid (6) arrives whole screw (5) from outside.

Description

Door closer or door operators
Technical field
The present invention relates to a kind of door closer or door operators, it to have at first end by the housing of closed with covers, is supported on the spring in this housing and the spring take-up for this spring.
Background technology
Door closer or door operators have the attachment hole for making attachment screw pass through in its housing usually.Due to narrow and small hole dimension, described attachment hole is arranged in the fringe region of housing.Therefore, very little space is only retained in this region for arranging spring take-up.
Summary of the invention
Therefore, the object of this invention is to provide a kind of door closer or door operators, wherein, even long and narrow hole type, still can realize suitable spring take-up.
According to the present invention, this problem solves by a kind of door closer or door operators, its have one end by the housing of closed with covers, be supported on the spring in described housing and the spring take-up for this spring, wherein this spring take-up comprises adjusting nut, this adjusting nut can be supported on adjustment screw rotatably, and wherein this adjustment screw props up the shoulder hole by lid and can arrive from outside through this lid.
Due to this structure, the contact point of adjustment screw is transferred to enclosure interior, even make the attachment screw of long and narrow hole type, also can realize the possibility suitably adjusting spring.
Dependent claims comprises the favourable further improvement of the present invention and embodiment.
According to preferred embodiment, the larger diameter of shoulder hole is positioned at the side place directed laterally that the side place directed to the inside of lid and the small diameter of shoulder hole are positioned at lid.
According to more preferred embodiment, the larger diameter of shoulder hole is converged by the small diameter of horizontal shoulder and shoulder hole, and adjustment screw props up by described shoulder with its head.Therefore, adjust screw reliably supported in the lid and can prop up by this lid.In addition, adjust screw can prevent from coming off.
In order to adjust the pretension of spring, according to favourable embodiment, adjustment screw has polygonal grooves, and adjustment instrument has from the path of external engagement this groove.Advantageously, described polygonal grooves can be configured to hexagonal indentations.Due to this measure, can from outside easily and adjust the pretension of spring rapidly.
In order to ensure the more secure support for whole screw at lid place, according to further advantageous embodiment, adjustment screw has support shoulder, and adjustment screw additionally props up the inner side by lid by means of this support shoulder.
According to favourable embodiment, adjustment screw is provided with circumferential groove joining the part place in shoulder hole to, in this circumferential groove, be provided with joint ring.This layout allows to realize liquid-tight seal.
Accompanying drawing explanation
With reference to accompanying drawing, other details, features and advantages of the present invention will become apparent in the following description, wherein:
Fig. 1 shows creative door closer or the view of door operators, and
Fig. 2 shows by according to the creative door closer of Fig. 1 or the sectional drawing of door operators.
Detailed description of the invention
Fig. 1 illustrates creative door closer and door operators.Door closer or door operators have housing 1, and this housing 1 can be attached on door, doorframe or similar item by attachment screw 2.
Wherein, in the housing 1 of door closer or door operators, be provided with spring 3, this spring props up by adjusting nut 4 with its one end.This adjusting nut 4 is rotatably supported on adjustment screw 5.Adjustment screw 5 is placed in shoulder hole with its head, and shoulder hole is arranged in lid 6, and housing 1 is closed at one end place of housing 1 by lid 6.
Shoulder hole has with a larger-diameter part and a part with small diameter, wherein directed to the inside towards spring 3 with larger-diameter part, and directed laterally with the part of small diameter.
The larger diameter of shoulder hole is converged with small diameter by horizontal shoulder 7.Adjustment screw 5 props up by described horizontal shoulder 7 with its head.
Polygonal grooves 8, be preferably hexagonal indentations and be mounted in the head of adjustment screw 5, adjustment instrument can be inserted into polygonal grooves 8 from outside by lid 6.
In addition, this adjustment screw 5 has support shoulder 9, and screw props up the inner side by lid 6 by this support shoulder.Therefore, one side adjustment screw 5 props up the shoulder 7 by shoulder hole with its head, leans on the inner side of lid 6 on the other hand by supporting shoulder 9.
Be provided with circumferential groove 10 at the part place joined in shoulder hole of adjustment screw 5, in this circumferential groove 10, be provided with joint ring.
Due to embodiments of the invention, adjustment instrument can be inserted through lid 6 and to enter the polygonal grooves 8 of adjustment screw 5 and to change the pretension of spring 3 from outside.
Foregoing description of the present invention is only for illustrative purposes, instead of is intended to limit the present invention.When not departing from the scope of the invention and its equivalent, various change within the scope of the invention and variant are all possible.
